TRITURATOR.

SPECIFICATION forming part of Letters Patent No. 774,067,

dated November 1, 1904.

Application led December 23, 1903. Serial No. 186,819. (No model.) g

To all whom t may concern:

sure a proper reduction of the substance to be treated by causing the pestle to be moved across the bottom of the mortar very rapidly on giving the pestle a pounding motion or allowing the pestle to work on the sides of the mortar or to pass slowly across the entire bottom or up the sides of the mortar, according to the nature ofthe substance under treatment, to insure perfect grinding without danger of clogging or cramping or Vfouling the machine, especially when treating gummy substances.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the triturator, Fig. 2 is a plan view of the same. Fig. 3 is an elevation of one end of the machine. Fig. 4 is a like view of the other end of the machine, and Fig. 5 is a face view of a set of interchangeable cams for use in the machine according to the nature of the substance to be triturated.

The mortar A, in which operates a pestle B, is set with its base on a disk C and held centrally thereon by set-screws C, and from the bottom of the disk C depends a shaft I), journaled in suitable bearings carried by a bracket E and the base E of the machine, as plainly illustrated in Figs. 1 and 3. On the shaft D is secured a bevel gear-wheel D', in mesh with a bevel gear-wheel F, fastened on the main shaft F of the machine and journaled in suitable bearings on the bracket E, the said main shaft F carrying a pulley F2, connected by belt with other machinery for imparting a rotary motion to the shaft F. The rotation of the latter is transmitted by the gear-wheels F and D to the shaft D,and consequently to the disk C and the mortar, A to provide a revoluble mortar, in which operates the revoluble pestle B, as hereinafter more fully described.

The pestle B is journaled with the upper end of its shank B' in a bearing G, provided. with trunnions G', journaled in one end of a walking-beam H, hung on ashaft H', carried by a standard E2, Verected on the base-plate E'. A spring G2 is coiled on one of the trunnions G and secured at one end of the walking-beam and presses with its other end on the shank of .the pestle B to hold the same in contact with the side of the mortar A, as will be readily understood by reference to Figs. I and 3.

The outer end of the walking-beam H is connected by a link I with the free end of a lever J, fulcrumed at J f on the standard E2, and on the said lever Jis journaled a anged friction-roller J2, engaged by the peripheral face of one of a set of cams K of different shapes and -adapted to be interchangeably secured on a shaft L, journaled in suitable bearings on a bracket E2, attached to the baseplate E.

On the shaft L -is secured a sprocket-wheel L', connected by a sprocket-chain L2 with a sprocket-wheel L2, secured on a shaft N, eX- tending transversely and journaled in the lower portion of the standard E2. On the shaft N is secured a sprocket-wheel N, connected by a sprocket-chain N2 with asprocketwheel N2, fastened on the main shaft F, so that when the latter is rotated a rotary motion is given to the shaft N, and by the connection described the shaft N causes rotation of the cam-shaft L for the cam K to impart a swinging motion in a downward direction to the lever J to cause the link I to rock the 'walking-beam H and move the pestle B up or down in the mortar A.

The pestle B is revoluble and is driven from the shaft N, and for the purpose described the shank B of the pestle is provided with abevel gear-wheel O, in mesh with a bevel gear-wheel (Y, mounted to turn loosely on one of the trunnions G, and on the bevel gear-wheel O is secured a sprocket-wheel O, connected by a sprocket-chain O3 with a sprocket-wheel 0", mounted to rotate looselypn the shaft H', which forms the fulcrum for the walkingbeam H. On the shaft of the sprocket-wheel O1 is secured a sprocket-wheel 05, connected by a sprocket-chain O with a sprocket-wheel O7, secured on the shaft N, so that when the latter is driven from the main shaft F, as previously explained, then a rotary motion is given by the sprocket-wheel O7, sprocketchain O, sprocket-wheels Oand O, sprocketchain O", sprocket-wheel O2, and gear-wheels O' and 0 to the pestle B, so as to rotate the latter in an opposite direction to the rotation of the mortar A and at the time the pestle B moves up and down by the action of the wall;-

ing-beam H.

It will be seen that by having an irregularly-shaped cam K an irregular rocking motion is given to the wallingbeam H, and consequently an irregular rocking movement to the pestle B to allow of moving the latter rapidly up or down or slowly up and down or very rapidly up or down, according to the nature of the substance to be triturated.

It is understood that when the main shaft F is rotated as described then a rotary motion is given to the mortar A, and at the same time the pestle B is rotated and moved up and down by the action of the walking-beam H,

having an irregular movement caused by the shape of the corresponding cam K, held detachably on the shaft L, as before explained.

The machine described is very simple and durable in construction, and a very effective reduction or trituration of the substance is had by the action of the revolving mortar A and the revolving' and up-and-down moving` pestle B, pressed on by the spring (i2.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. A triturator having a revoluble mortar, a pestle,1neans for rotating the pestle, and means for moving the pestle up and down and a spring' pressing' the pestle laterally against the mortar, as set forth.
